AUGUSTA, Maine (AP) — The owner of the Kennebec Arsenal says he has plans to redevelop five of the eight buildings at the long dormant site over the next three years.

Tom Niemann submitted the plan in response to a letter from the Office of the Maine Attorney General that threatened a lawsuit if his North Carolina firm, Niemann Capital, didn't take steps to prevent further damage to the Augusta property by Oct. 1.

State officials agreed to extend that deadline by three weeks, and Niemann tells the Kennebec Journal (http://bit.ly/TbcxO2 ) he submitted his plan for the complex on Oct. 22 — the last day of the deadline.

A spokeswoman for the attorney general says Niemann's plan is under review and had no further information.
